On 26-27 October, 2015, the Department of Electric Engineering of the Technical University of Denmark (DTU) hosted an International Energy Agency (IEA) workshop on V2X technology with forty-six experts from academia, the system operator domain and the car industry.
The term “V2X” (vehicle to everything) is used to cover a number of applications where an Electric Vehicle (EV) battery can be used as a power source. This function strengthens an EV’s ability to support the power system since power and energy can be provided from the battery. It also means that the EV owner will have access to electric power where a connection to the power grid is not practical or possible. The International Energy Agency (IEA) has created a task to investigate V2X as one of the key technologies that will help the EV to realise its potential in a smart grid context.
During the workshop, the Department of Electric Engineering together with its partners in the Danish Nikola project demonstrated that two series-produced EVs (Nissan Leafs) could use V2X to provide frequency regulation. In the demonstration that was carried out in the new EVLab facilities (part of the PowerLabDK platform), power was sent back into the power system when the frequency went below 50Hz, meaning that there was a demand for power in the electric grid.
This proof of concept is important since it shows that thousands of Danish Nissan Leafs are already capable of providing advanced V2X-based smart grid services. Ultimately such services should aid the operation of the future Danish power system while reducing the cost of ownership for EV owners.
